Background We sought to evaluate the intermediate term outcomes of trapeziectomy with double Mini TightRope suture suspensionplasty and flexor carpi radialis to abductor pollicis longus imbrication for the treatment of basilar thumb joint arthritis.

Case Description We performed a retrospective review of patients from 2012 to 2021 at a single institution within a standardized protocol. Thirty-nine patients (46 thumbs) with a mean age of 61 years and clinical follow-up of 2.8 years met our inclusion criteria. Grip strength increased from 13.8 kg preoperatively to 20.3 kg postoperatively. Appositional pinch strength increased from 3.7 to 5.7 kg, while oppositional pinch strength also increased from 2.8 to 4.4 kg. Trapezial space ratio was well maintained at 0.36 postoperatively compared with 0.46 preoperatively at a mean radiographic follow-up of 2.2 years.

Literature Review and Clinical Relevance Results from our series demonstrate predictable outcomes with reduced pain levels, increased grip and pinch strengths, improved function, and preserved range of motion with few complications.

Level of Evidence III therapeutic.

Trial Registration Not applicable.
